Any surgical technique intended to correct vision issues is vision correction surgery, commonly known as refractive and laser eye surgery. Tremendous progress has been made in this subject in recent years. Thanks to refractive and laser eye surgery, many individuals can now see better than before. It is because the cornea, the clear front section of the eye, is reshaped in most types of vision correction surgery. It allows light to pass through and focus properly on the retina at the back of your eye. Below is a list of the most prevalent varieties of vision correction surgeries like LASIK, RELEX SMILE, PRK, etc.
People who are nearsighted, farsighted, or have astigmatism can benefit from LASIK or laser in-situ keratomileusis. The surgeon creates a flap in the cornea to access the tissue beneath the cornea’s outer layer. The tissue beneath your cornea is then reshaped with a laser so that it can focus light appropriately. The flap is what distinguishes LASIK from other surgeries. The surgeon may also employ the wavefront technique, a sort of computerized scanning, to build a detailed image of your cornea to use as a reference.
- Relex SMILE
In Relex Smile surgery, the Visumax femtosecond laser is used to construct a corrected tissue lens within the cornea. This is subsequently removed through an incision, which helps to maintain the cornea’s nerve endings. Since the cornea’s surface is so delicate, it’s critical to treat it with special attention and care. Even the tiniest sensation on the cornea can cause rapid discomfort. As a result, SMILE is a fantastic option because it lowers the risk of irritation and dry eye symptoms. In India, the Relex SMILE cost is around Rs 50,000 per eye.
Intrastromal corneal ring segments (ICRS) inserted into the cornea’s mid-layer are known as Intacs. These are micro-thin, semi-circular rings that can aid in resolving the vision problems caused by keratoconus, a progressive eye disorder. ICR was once employed to correct nearsightedness, but laser-based techniques have since taken their place. It’s now being tested to see if it can help with keratoconus, a condition in which your cornea thins and causes vision loss.
PRK or photorefractive keratectomy is a laser eye surgery that changes the cornea’s curvature to repair refractive vision defects. The cornea is responsible for refracting light toward the retina’s center, and refractive errors occur when the refraction is off-center due to the cornea’s shape. PRK modifies the cornea’s shape to ensure that light bends correctly. This surgery can be conducted on patients having Myopia, hyperopia, and astigmatism.
- PRELEX and RLE
Refractive lens exchange is an abbreviation for refractive lens exchange. PRELEX, clear lens exchange (CLE), precise lens extraction (CLE), and refractive lens replacement are some of the other names for this procedure (RLR). The process is similar to cataract surgery. First, the doctor makes a tiny cut on the edge of your cornea. Next, your natural lens is removed and replaced with a plastic lens implant. It can correct extreme farsightedness or nearsightedness with this treatment. PRELEX, or presbyopic lens exchange, treats presbyopia or the lack of eye flexibility. Finally, your lens is removed and replaced with a multifocal lens by the doctor. It’s the same as the RLE, but with the addition of a multifocal implant to help you see both far and close.
Our vision is precious! Many people lose their vision due to cataracts. Entrepreneur Mr. Tej Kohli formed the “Tej Kohli & Ruit Foundation” with the association of avid eye surgeon Dr. Sanduk Ruit. Mr. Tej Kohli is the sole fundraiser of this organization and they conduct free eye surgery camps for poverty-stricken people so that they can eliminate cataract blindness.
